Embodiment Construction
[0030]Referring to FIG. 1, the preferred embodiment of a multi-antenna system 100 according to the present invention is a planar antenna system operable in first and second frequency bands ranging from 2400 MHz to 2484 MHz and from 5150 MHz to 5825 MHz, respectively, is preferably fabricated using printed circuit board (PCB) techniques, and includes an antenna module 10 and a system module 20.
[0031]The antenna module 10 includes a substrate 1 and a plurality of planar dipole antennas 2. In this embodiment, the substrate 1 includes opposite first and second surfaces 11, 12, is formed with a through hole 13 for extension of signal-feed cables 6 therethrough, and is preferably made of dielectric materials, such as glass fiber (FR4). In addition, the antenna module 10 includes three planar dipole antennas 2 each being a half-wavelength dipole antenna. However, configuration of the planar dipole antennas 2 may be otherwise in other embodiments. Although the substrate 1 of this embodiment...
